Need to track when Auntie Flo is coming to visit?? These are perfect for that! These will work well in any planner or calendar. Each sheet includes 40 undies, in varying shades and 40 small teardrop shaped stickers. That is a total of 80! I mean, who really wants to spend more money on your menstrual cycle. You have the choice of removable matte, premium matte/vinyl or glossy paper.
